STPM34 weird values reading his registers
Hi,I'm debugging a board with two STMP34 used to read voltage and current from L1 - L2 and L3 of a threephase system. The current signals comes from three different TA devices.The issue is: sometimes, reading a block of registers using the Metro_HAL_...
WLC99Rx Stuck in DC Mode
I'm getting a STEVAL-WLC99RX and STEVAL-WBCTX70 configured for some testing and put the WLC99RX in DC mode (5V ono Vout). I cannot figure out how to get it back into Rx mode.It feels a little bit like a chicken and egg situation. I need to be in DC m...
Electrically Isolated Semiconductor Device - STGF15H60DF
I had previously asked in case # 00204067, if the subject part STGF15H60DF was UL approved for isolation and I was told that is was approved under UL catigory QQQX2.E81734 per the requirements of UL 1557. I was linked to UL File # E81734 with a highl...
I didn't found documentation about coding of the L9966 SPI interface.
L9966 has one spi interface to work with MCU's, but I need to know how it is working an d I didn't find documentation about it. Can somebody tell me where to find it?
GP244
Hi,This is a over voltage diode from a uC programmer that I blew. Can anyone tell me the value? Thank you for the help,Rob
L6235Q - Using DIR with PWM signal (DT0001)
I found an aplication (ST Design Tip - DT0001), that suggests a way of controlling motor speed, using a PWM signal on the DIR input. Works fine for speed. Note: we are not using a micro as shown in the DT90001. We are using our design. And using P...
EVALSTPM34 boards work unstable when using single Clock source
Hello, I am trying out a 220 V power measurement set up with 3 STPM34 evaluation boards. I need to use as less wires as possible, so I am using SPI with 3 different CS and 1 SYN pin. I am also trying to reduce component count by using only 1 CLK sour...
Resolved! L6902 component choice
Hi, I'm designing a DIY switching power supply around the L6902. Intended output voltage is <22V, input voltage 24V, output current in constant current mode between 0.6 and 0.8A.My questions:the datasheet shows an inductor value of 22uH, is this valu...
Getting started with the STDES-30KWVRECT 30 kW Vienna PFC rectifier reference design UM3011
I am working on Vienna PFC rectifier and was studying ST Microelectronics application note UM3011.In the note equn. (9) is given as while my working on these equations I got following results If someone can go through my derivations in attached file ...
Resolved! Using MPP on stwlc38
Is it possible to use a Qi2 rx coil with magnetic array on a stwlc38 design? The goal is to use a Qi2 charger and reap the benefits of magnetic alignment and 15W charging while still being on the Qi1.3 standard of the stwlc38.
